A three-year varsity letterwinner for the GW men's basketball
team, Manning helped the Colonials to a 66-16 record from 1954-56. He
played in eight games as a sophomore on the 1953-54 Colonials team that
went 23-3 overall, peaked at No. 7 in the Associated Press national
rankings, won both the Southern Conference regular-season and tournament
titles and earned the program's first NCAA Tournament bid. He capped
his GW career averaging 10.0 points and 6.8 rebounds in 24 games on the
1955-56 team that went 19-7 and won a share of the Southern Conference regular season title.

He returned to earn a Doctorate in Education at GW after
spending time in the Army and in training camp with the NBA's Boston
Celtics. Manning then went on to leave a legacy as an educator and
principal at high schools throughout Northern Virginia, primarily at
Langley High School, and was an adjunct professor at GW, Marymount and
Virginia mentoring future secondary education administrators.
